A new central air system in Centennial typically runs $5,500 to $12,000 installed. The final price depends on your home's size, the SEER2 efficiency you choose, the condition of your existing ductwork, and the brand. We provide a written, itemized estimate after an in-home assessment, and financing is available to spread the cost over monthly payments.
Most straightforward AC replacements in Centennial are completed in a single day. Jobs that involve ductwork changes, electrical upgrades, or a switch to a different system type can take longer. We give you a clear timeline with your estimate so you know exactly what to expect before we start.
The right size comes from a Manual J load calculation, not a rule of thumb. We measure your home's square footage, insulation, windows, and orientation, then apply an altitude derate for Centennial's elevation above 5,800 feet. Proper sizing prevents the short cycling and humidity problems that come with an oversized unit and the constant running of an undersized one.
Xcel Energy offers rebates on qualifying high-efficiency cooling equipment, and the amount depends on the system and its efficiency rating. If you are open to a heat pump, the savings grow further because heat pumps stack Xcel rebates with the federal tax credit. We walk every Centennial customer through the rebates that apply to their specific installation.
We install Ruud for strong value, Carrier for premium variable-speed comfort, and Armstrong Air for durable, U.S.-built mid-tier systems. Because we are authorized for all three, we recommend based on your home and budget rather than a single product line. During the estimate we match the brand and efficiency tier to how you use your home.
If your furnace is also aging, replacing both together can make sense. The AC coil sits on the furnace, and a matched system runs more efficiently than mixing new and old equipment. It also saves a second installation labor charge. We will give you an honest read on whether your current furnace has good years left or whether a matched replacement is the smarter long-term move.
